title: Norwood-sano operation using a stentless pulmonary valved conduit.
abstract: The Sano modification of Norwood's operation has the potential to generate an excess volume load on the single right ventricle as a consequence of diastolic reversal of flow through the conduit. This article describes the use of a new, small, biological conduit with a porcine valve inside. This new conduit has been used in modified Norwood procedures. It is interposed between the right ventricle and the confluence of the pulmonary arteries. The use of a valved conduit should prevent the retrograde diastolic blood flow observed with use of nonvalved conduits and may improve postoperative hemodynamics. The use of a new stentless valved conduit in 3 recent Norwood procedures is reported herein.
